Sanggenon C 是一种从桑属的根皮中分离得到的黄烷酮 Diels-Alder 加合物化合物。Sanggenon C 可抑制NF-κB 活性,抑制 RAW264.7 细胞中诱导型一氧化氮合酶的表达,以及肿瘤坏死因子-α 刺激的细胞粘附和血管细胞粘附分子-1 的表达; Sanggenon C 还具有抗氧化和抗炎作用,也有抑制胰脂肪酶作用。[1,2]
MitoPBN is a mitochondria-targeted antioxidant. It accumulates in the mitochondria following the generation of a mitochondrial membrane potential by succinate, an effect that is blocked by addition of the mitochondrial membrane potential uncoupler FCCP . MitoPBN inhibits superoxide activation of mitochondrial uncoupling protein 1 (UCP1), UCP2, and UCP3 when used at a concentration of 250 nM in vitro but does not react with superoxide. It traps hydroxyl (IC50 = ~77 μM) and carbon-centered radicals and inhibits the initiation of lipid peroxidation in isolated bovine heart mitochondria.
